You most probably need a driver disk; searching for the model and 'RHEL
driver' tells me that you need a "Driver Diskette for HP ProLiant Smart
Array Controller", which you can get at hp.com.

You then need to burn it onto CD or copy it to an USB stick (don't know
that piece of driver), so you can load this driver when booting CentOS.
You'll need to boot Linux with the 'dd' option ('dd' stands for 'driver
disk') when you see grub.
